o QML QJ Patented Apr. 11, 19353 unrran STATES PATENT OFEICE WENDELL L. MARTIN, OF CLEVELAND, OHIO, ASSIGNOR TO THE MARTIN BROTHERS ELECTRIC COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO DRIER Application filed June 25,

My invention relates to driers and more particularly to driers for the hair, and has for its principal object the provision of a new and improved construction of this type.

In the drawings accompanying this specification, and forming a part of this application, I have shown, for purposes of illustration. one form which my invention mayiassume. and in these drawings:

Figure 1 is a longitudinal vertical sectional view of one embodiment of the drier, corresponding substantially to the line 11 of Figure 2,

Figure 2 is a front elevational view of the embodiment illustrated in Figure 1,

Figure 3 is a transverse yertical sectional view ot the embodiment. corresponding substantiallv to the line 3--3 of Figure 1, while Figure r is a diagrammatic view of the electrical devices utilized in connection with said emlmdiment.

.\s illustrated in the embodiment herein shown 10 indicates a skeleton housing having openings 11 in its side walls, a rear wall 12,

and a forward edge exteriorly rabbeted as at 13 for the reception of a flange 14 of a casing 15. secured to the housing 10 by screws 16. Mounted in the housing 10 is a motor 17 having a suction fan 18 arranged at its '30 forward end and connected to its armature shaft 15). and also having a block 20 affixed to its opposite end, provided with a threaded stud 21 projecting through the rear wall 12 of the housing 10 and secured by a nut 22,

thereby supporting the motor 17 centrally within the housing.

The casing 15 is of substantially parabolical formation, provided at its forward end with an annular transversely curved grating 23, secured to the forward edge of the casing by screws 24, and provided with inlet open ings and connected to the inner periphery 26 of the grating 23, by a rabbet joint 27, is a second, interiorly disposed, annular grating 28 secured to the casing 15 as at 29, and

having openings 30 leading into the interior or" the casing 15. The grating 28 is also transversely carved in a direction opposite to the curve of the grating 23, and forms with the grating 23, and adjacent portion of the 5g casing 15. an annular compartment 31, having a screen 32 therein, extending over the openings 25 and 30, and fastened by screws 33. Arranged in the compartment 31 is an annu ar heating coil 34, supported in position by brackets 35 carried by the grating member 23. Dividing the casing 15-andthe housing 10 is a. partition 36 having a central opening 37 leading from the casing 15 into the housing 10, and covered by a'screen 38 59 fastened to the rear side of the partition 36 by bolts 39.

The inlet means, comprising the gratings 23 and 28, compartment 31, and-openings 25 and 30, thus define an entrance-way 60 to permit the head of the patient to be inserted well into the operating chamber 61 defined by the interior surface of the casing 15 and the partition 36. Thus when the motor 17, located at a remote point from the entrance- 7 way 60, is energized, air will be drawn into the casing through said inlet means, traverse the operating chamber 61 from front to rear, passing about the head of the patient, finally emerging from the rear of the chamber 61 through the opening 37 in the partition, and into the housing 10, and out. of said housing 10 through the openings 11.

At the forward side of the partition 36 is a bracket 40 fastened by the bolts 39, carrying a block 41 provided with radially disposed sockets for the reception of therapeutic lamps 42. The casing 15 is further provided with cut-out portions 43 opening into small enclosure members 44, secured to the housing 15 by bolts 45, and each carrying a bulb socket 46 accommodating a lamp 47. Attention is drawn to the fact that the lamps 42 and 47 are also remote from theentrancewvay '60, yet direct their energy toward said entrance- In-a-ll'prior structures of which I have know].-

edge, the energy of the lamps is directed in the'same direction as that in which the air is traveling, resulting in rapid dissipation ofsaid energy and lowering of efficiency of the drier.

The electrical circuit for the motor 17, lamps42 and 47, and heating coil 34, is illustrated in diagrammatic form in Figure 4, and comprises a line wire 48 connected by a branch 49, with the motor 17, a conductor 50 leading from the motor 17 to an arcuate terminal 51 of a switch 52, the movable lever 53 of which is connected with the line wire 55. The lamps 42 and 47 are interposed in a circuit comprising a branch 56 in communication with the line wire 48 and a conductor 57 leading'to'the switch terminal 58, adapted to be connected with the line wire through the movable lever 53 of the switch. The heating element 34 is connected at one end to the conductor 57, and at its opposite end is connected by a conductor with a switch terminal 71, adapted to be connected with the line wire 55 through the lever 53;

With this arrangement the motor may be run without energiz-ation of the heating element 34 and lamps 42 and 47, the circuit in this condition comprising the line wire 48,

branch 49, motor 17, conductor 50, terminal 51, and lever 53 of the switch and line wire 55. The lamps 42 and 47, may be thrown in circuit by moving the member 53 of the switch along the arcuate terminal 51, and also into engagement with the terminal 58, in which event the lamps 42 and 47 will be energized as well as the motor 17. The heatin g element 34 may be included in circuit with the motor 17 and lamps 42 and 47 and by mov .ing the lever 53 farther along the arcuate terminal 51 and also into engagement with the terminal 71, and the heating element 34 will be energized as well as the motor 17 and lamps 42 and 47.

' In operation,'the head of the person to be I treated is inserted well into the casing 15, and

assuming that the motor 17, heating element 34, and lamps 42 and 47 are energized, the

suction fan '18 and draw air inwardly through the openings 25, into the compartment 31. where it is heated, thence through the openings 30, into and through the operating chamber 61, and about the head of the the person operated upon; the air thence passing through the central opening 37 into' the housing 10, and out of the housing 10 through the openings 11.

From the above discussion it will be observed that the air is drawn through the inlet means, and traverses the operating chamber 61 from front to rear, passing over and about the head of the person operated upon, and is then discharged from the housing 10; during this operation the lamps 42 and 47 direct their energy toward the head of the person operated upon, and in a direction toward the entrance-way 60, and in a direction opposite to the direction of travel of the air in traversing the operating chamber 61, the air and the energy from the lamps thereby working in opposite directions and overcoming the tendency of the stream of air to rapidly dissipate the energy of the lamps.

From the above description it will be apparent to those skilled in the art that I have disclosed one embodiment which achieves at least the principal object of the invention; it also will be apparent to those skilled in the art that the invention is susceptible of other uses than thoseherein disclosed and may be variously changed and modified, all withoutv departing from the spirit of the invention; hence it will be understood that said embodiment is illustrative only, and that my invention is not limited thereto.
